The concealed sprinkler is composed of glass bulb sprinkler, screw sleeve seat, outer cover seat and outer cover. The sprinkler and screw socket are installed on the pipeline of the pipe network together, and then the cover is installed.
installation environment
Concealed fire sprinkler is suitable to be installed in places with luxurious decoration, high appearance requirements, limited space and exposed sprinkler easily cause collision, such as hotels, clubs, office buildings, entertainment centers, etc.
working principle
The sprinkler head and the screw sleeve are installed on the spray pipe road together, and then the outer cover is installed. The outer cover seat and the outer cover cover (decorative cover) are welded into one by fusible alloy. When the fire occurs, the ambient temperature rises and the melting point of the fusible alloy is reached, the outer cover (decorative cover) will fall off automatically, and the splash tray of the sprinkler head will move down. As the temperature continues to rise, the glass ball sprinkler head inside the cover will be broken because of temperature sensitivity and liquid expansion, thus opening the sprinkler head to spray water automatically.
